- Page 3 Introduction The TC-9102 series of microprocessor-based controllers is designed for the control of Fan Coil Units (FCUs) with heating and cooling, and a single-speed, 3-speed or variable-speed fan. The controller can regulate water valves, one or 2-stage electric heating, or a cooling unit where the compressor has its own short cycle protection.
- Page 4 2333 Figure 3: TM-9180 Room Command Module The TC-9102 Controller is available in several model types according to Model Types the type of outputs and the range of the integrated or remote set point input. Refer to Ordering Codes at the end of this bulletin for details. Technical Bulletin—TC-9102...
- Page 5 The controller can be connected to a Room Command Module, from Controller which it receives the room temperature, the remote set point and other Functions override signals. The TM-9180 intelligent Room Command Module provides these signals via a serial bus connection to the controller. The other Room Command Modules (TM-9150/9160/9170) provide the signals as individually connected physical inputs to the controller.
- Page 6 Standalone The controller operates in standalone mode when it is not connected to a Mode supervisory system via the communications bus nor to a TM-9180 Room Command Module. In standalone mode the controller may operate in one of three control modes: •...
- Page 7 Controller Set The set point in all control modes may be modified from the integrated Points set point adjuster or from the remote set point dial/control panel on the Room Command Module, according to the controller model type. The controller models with a remote set point of 12-28°C require that a Room Command Module or an external potentiometer is connected to give the set point.
- Page 8 Alternate Mode When pressed for about one second, the occupancy button on the Room Command Module changes the mode of operation of the controller to the “Alternate Mode” or back to the normal “Control Mode” as shown in Table 2. The “COMFORT (T)” alternate mode is active only for a period of one hour, after which the controller reverts to the normal control mode.
- Page 9 Winter/Summer When the controller is connected to a supervisory system, the winter Compensation and/or summer compensation modes may be enabled. The supervisory system must be programmed to set the outdoor air temperature via the communications bus on a periodic basis. After a power interruption the winter and summer compensation modes are temporarily disabled until a new outdoor air temperature value is received.
- Page 10 Auto-dial When the controller is connected to a remote N2 Bus and supervised by a Feature Metasys N2 Dialer (NU-NDM101-0) which is linked to a Metasys network by a telephone line, the following alarm conditions in the controller will initiate the automatic dial feature: •...
- Page 11 PAT - Position The PAT output is a pair of triacs which are switched on to open and Adjust Type close an incrementally driven heating or cooling valve. The duration of switching is directly proportional to the change in the controller output and related to the full stroke time of the valve such that a 100% change will completely open or close the valve.
- Page 12 Fan Output Types Fan On/Off The output is a normally open relay contact which closes when the fan is required to run. Terminals are provided to connect the fan supply voltage to the controller in order to facilitate the wiring to the fan motor. The fan supply voltage is not used within the controller.
- Page 13 0 to 10 VDC The output is a control signal for driving a fan speed controller with an Control Signal opto-isolated 0 to 10 VDC input. As the output voltage increases, the fan speed controller must increase the speed of the fan from the minimum speed of the fan motor to its maximum speed.

Users should ensure that all Johnson Controls' products are used safely and without risk to health or property. For surface mounting, slide the two mounting brackets into the slots at Mounting opposite corners of the controller base behind the terminals. - Page 16 Note: A minimum of 25 mm of space is required above and below the controller for the removal of separable terminals. Technical Bulletin—TC-9102...
- Page 17 Before connecting or disconnecting any wires, ensure that all power Wiring supplies have been switched off and all wires are potential-free to prevent equipment damage and avoid electrical shock. Terminations are made on the terminal blocks, at the top and bottom of the controller, which accept up to 1.5mm wires.
